They continue yellowing and I have raised the concern in questions. People say it may be natural cycle ending , but northern lights seem to have some more time to go. I fed them EC 1,3-1,4 a day before posting. I will stop watering every day , seems like even low nutrient solution lead to build up , even though I did flush. Doing nutes-water -nutes till the end flush.
Fellows, please also let me know , is this result fine , considering the fact I was dragging them with 300W this whole time and installed the 600w light a week ago ?
